Subject: [PATCH v2 07/13] OMAP: hwmod: don't auto-disable hwmod when !CONFIG_PM_RUNTIME
Date: Thu, 24 Jun 2010 16:44:38 -0700	[thread overview]
Message-ID: <1277423084-25528-8-git-send-email-khilman@deeprootsystems.com> (raw)
In-Reply-To: <1277423084-25528-1-git-send-email-khilman@deeprootsystems.com>

When runtime PM is disabled, the pm_runtime_idle() and _enable()
functions will be effectively noops and will not result in enable
and idle calls at the hwmod level.

In order for drivers to still work when runtime PM is disabled, ensure
that all hwmods are left in an enabled state so that even without
runtime PM management, they will still work.
